Work area safety
Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust
or fumes.
Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
Electrical safety
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with ea r thed
(grounded) power tools. Unmodified plugs
an d matc hing outlets will reduce risk of
electric shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
When operating a power tool outdoors,
use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of
an GFCI reduces the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and
us e common sense when ope rating a
power tool. Do not use a power tool while
you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention
while operating power tools may result in
serious personal injury.
Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes,
hard ha t, or hear ing p rotection used for
appropriate conditions will reduce personal
injuries.
Prevent unintentional starting. Ensure the
sw itch is in the off-po sitio n before
connecting to power source and / or battery
pack, pick ing up or carry ing the tool.
Carrying power tools with your finger on the
switch or energizing power tools that have the
switch on invites accidents.
Re move a ny adj ustin g key or wrench
before turning the power tool on. A wrench
or a key left attached to a rotating part of the
power tool may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better
co n trol o f the power tool i n unexp ected
situations.
Dress properly. Do not wear loose clothing
or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in
moving parts.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-
related hazards.
Power tool use and care
Do n ot force the powe r tool. U s e the
correct power tool for your application.
The correct power tool will do the job better
and safer at the rate for which it was designed.
Do not use the power tool if the switch does
not turn it on and off. Any power tool that
cann o t be controll e d with the switch is
dangerous and must be repaired.
Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.

Safety Rules for Orbital Sanders
Unplug th e sand e r before ch anging
accessories. Accidental start-ups may occur
if sander is plugged in while changing an
accessory.
Us e clam ps or other practical w ay to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control.
If your tool is equipped with a dust bag,
empty it frequently and after completion
of sanding. Be extremely careful of dust
disposal, materials in fine particle form may
be explosive. Do not throw sanding dust on
an open fire. Spontaneous combustion, may
in time, result from mixture of oil or water
with dust particles.
Always wear eye protection and a dust
mask for dusty applications and when
sanding overhead. Sanding particles can
be absorbed by your eyes and inhaled easily
and may cause health complications.
Use special precautions when sanding
chemically pressure treated lumber, paint
th at may be l ead based, or any other
materials that may contain carcinogens. A
suitable breathing respirator and protective
clothi n g must be worn by al l perso n s
entering the work area. Work area should be
sealed by plastic sheeting and persons not
protected should be kept out until work area
is thoroughly cleaned.
Do not wet sand with this sander. Liquids
entering the motor housing is an electrical
shock hazard.
Do not use sandpaper intended for larger
sanding pads. Larger sandpaper will extend
beyond the sanding pad causing snagging,
tearing of the paper or kick-back. Extra paper
extending beyond the sanding pad can also
cause serious lacerations.
Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment
or binding of moving parts, breakage of
parts and any other condition that may
affect the power tool’s operation. If damaged,
have the power tool repaired before use.
Many acc i d e n ts a r e ca u sed b y po o r ly
maintained power tools.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
Use the power tool, accessories and tool
bits etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified
repa i r pers o n usin g only identic a l
replacement parts. This will ensure that the
safety of the power tool is maintained.
SM 2610952199 05-12_SM 2610952199 05-12 6/26/12 8:39 AM Page 3
GFCI and personal protection devices like
electrician’s rubber gloves and footwear will
further enhance your personal safety.
Do not use AC only rated tools with a DC
power supply. While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a hazard
to the operator.
Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely
control the power tool.
Develop a periodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of
th e tool since int ernal wir es may be
misplaced or pinched or safety guard return
sp rings may be imp roper ly mou nted.
Certain cleaning agents such as gasoline,
carbon tetrachloride, ammonia, etc. may
damage plastic parts.
Risk of injury to user. The power cord must only
be serviced by a Skil Factory Service Center or
Autho rized Skil Service Station.
Some dust created by power
sanding, sawing, grinding,
drilling, and other construction activities
contains chemicals known to cause cancer,
birth defects or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and
other masonry products, and
• Arsenic and chromium from chemically-
treated lumber.
Your r i s k f rom these exposures v a r i es,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area, and
work with approved safety equipment, such as
those dust masks that are specially designed
to filter out microscopic particles.

FIG. 2
ABRASIVE SHEETS
Aluminum oxide, silicon carbide, or other
synthetic abrasives are recommended for
power sanding use. Natural abrasives, such as
flint or garnet sheet are too soft for economical
use in power sanding. For best results, use Skil
abrasive sheets: The uniform spacing between
grains minimizes filling or loading. The high
quality aluminum oxide sheet with heavy
backing, cuts faster and lasts longer.
The following are recommended abrasive
sheets and applications:
1. Coarse Grit: For rough wood sanding.
2. Medium Grit: For general wood sanding.
3. Fine Grit: For smoo thing wood or
plas ter patches.
4. Extra Fine Grit: For final sandin g bare
wood and smoothing old
paint.

Sanding Tips
This sander has been designed for even weight
distribution which virtually eliminates the use of
pressure. Excessive pressure to the sander
may result in an uneven sanding job and
premature grit wear. Constant and excessive
pressure can cause overheating and possible
damage to the motor as well as premature
wear out of the pad on hook and loop models.
It's usually best to work in strokes that parallel
the grain, using some lateral motion so the
main strokes are overlapped as much as 75%.
If the surface is rough, start sanding with a
coarse grit sheet, then medium and then finish
wi th a fine or extra fine abrasi ve. This
procedure will vary with different types of
materials and work. Continue to sand with each
grit until the surface looks uniform. When going
from one grit size to a finer size, do not skip
more than two sizes.
To remove the greatest amount of stock, use a
coarse grit and move the sander steadily over
the entire surface against the grain as well as
with the grain. DO NOT REMAIN IN ONE
SPOT TOO LONG. It may remove too much
materi al and un even sanding will result.
Sanding with the grain of the wood gives the
smoothest final finish.
Additional abrasive sheets can be conveniently
cut from large-size commercially available
sheets (standard size: 9" x 11-1/16"; 228 x
280mm). Cut into four pieces of equal size as
shown (Fig. 3). Choose the proper grit for the
job.
